IPC: G03B17/04
Filed: 1990-11-22
Abstract: PURPOSE:To restore the shape of a camera to that at a portable period even when a battery is exhausted to a state where photographing is impossible to make by providing a battery check circuit to check whether a source voltage is kept at a level at which a drive source for photographing is operable and a computing control circuit to receive an output from the battery check circuit and prohibit photographing operation, and setting a voltage level, at which a drive source for changing a shape is capable of driving, to a value lower than the level of a drive source for photographing. CONSTITUTION:When photographing is continued and the degree of consumption of a battery is increased, an output from a voltage detector IC 35 is reduced to a value insufficient in a battery voltage, and a CPU 1 prohibits a following sequence. In which case, when a barrier 41 is closed, a battery switch 26 is turned OFF, and the CPU 1 detects that a barrier is closed. In this case, a battery is checked in a state that a transistor 44 is turned ON and a second dummy load 45 is energized. In the load 45, a flowing current is reduced compared with a first dummy load 43, and reduction of a voltage is decreased. From an IC 35, a signal by means of which it is detected that a battery voltage is sufficient for containing of a lens is transmitted to the CPU 1, and a lens drive motor 11 is rotated for containing. This constitution restores a shape to that at a portable period even when photographing is impossible to make.

Abstract: PURPOSE: To exactly keep the carrier component of a reception signal and a regenerated carrier in a common-mode by frequency-dividing an inverse diffuse output and the regenerated carrier delayed by 90 degrees after the output and the carrier are multiplied. CONSTITUTION: An inverse diffuse carrier A that a reception signal is inversely diffused by an inverse spread code PN0 and the regenerated carrier B from a voltage control oscillator VCO 6 which is locked by the phase which is lagging behind the carrier A by 90 degrees are inputted in a phase detector 3 and a lock state is maintained. At the same time, the carriers A and B are inputted to a multiplier 7 and the carrier which is, in frequency, twice as high as the regenerated carrier and the inverse diffuse carrier is generated. A high frequency component C is extracted from the generated carrier through an HPF 10, the component B is inputted to a frequency-divider 8, the component is subjected to frequency division to 1/2, and a carrier D which has the common-mode with the inverse diffuse carrier is outputted.  Next, the carrier D is multiplied by the reception signal by using a multiplier 9 and a base band signal is obtained. Thus, the regenerated carrier which has the common-mode with the reception signal can be exactly generated, regardless of the phase accuracy that a phase shifter itself has and the phase deviation for a temperature change.

IPC: G06F12/00
Filed: 1992-11-04
Abstract: PURPOSE:To shorten data equalizing processing time and to improve the opera tion efficiency of a system. CONSTITUTION:Prior to data copying, a system B being transitted to a a hot stand-by state finds out a sector number to be copied and requests exclusive processing to a system A (1). The system A receiving the exclusive processing request memorizes the informed sector number as a copying sector number, uses the sector number for checking data-updating processing and returns exclusive processing OK to the system B. At the time of receiving OK, the system B copies the sector concerned (2). Then the system A starts the data equalizing processing of a stop side computer, compares the sector number in copying with the sector number to be updated before the updating, and when both the sector numbers coincide with each other, retries said processing after waiting several 10msec.

Abstract: PROBLEM TO BE SOLVED: To freely designate all phase angles and to keep them constant despite the change of frequency of an input signal by counting the time clock pulses and outputting an output pulse when the counted clock pulses reach the absolute phase number. SOLUTION: An input trigger circuit 1 acquires a standardized input pulse 11 from an input signal 9 and simultaneously resets an adder 4 and an up- counter 5. The adder 4 and counter 5 multiply N pieces of time clock pulses existing between two adjacent pulses 11 by a phase number 14 of value F that is equivalent to a desired phase angle ϕ and generated by a phase input circuit 2 and then divide this multiplication value by a number Z=2<b> that is produced from width (b) set between the circuit 2 and the adder 4. The relative phase integer P=N*F/2<b> which is outputted to a parallel data output terminal of the counter 5 is loaded into a down-counter 6. The counter 6 counts down the relative phase number and the time clock pulses and outputs a zero-pulse 17 to an output terminal TC when its count value is equal to zero.
